PROBLEM TO BE SOLVED: To eliminate odor of exhaust air in a suction vehicle safely, unfailingly, and easily.SOLUTION: A suction vehicle is provided with: a vacuum pump 10 a recovery tank 4 for storing a suctioned object which is suctioned by utilizing negative pressure of the vacuum pump 10 an exhaust passage 15 which exhausts air discharged from the vacuum pump 10 to the outside and a lubrication oil circulation passage 20 for sending a lubrication oil 50 including an odor modulation oil solution 50a which eliminates odor of the suctioned object to the vacuum pump 10. The suction vehicle is configured so that air containing the lubrication oil is discharged from the vacuum pump 10 to the exhaust passage 15.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】吸引車における排気の臭いを安全、確実かつ簡易に取り除く。【解決手段】真空ポンプ10と、真空ポンプ10の負圧を利用して吸引された吸引物を収容する回収タンク4と、真空ポンプ10から排出されるエアを外部に排気する排気通路15とを設ける。そして、吸引物の臭気を消臭する臭気変調用油剤50aを含む潤滑油50を真空ポンプ10に送り込む潤滑油流通路20を設ける。排気通路15に、潤滑油を含むエアが真空ポンプ10から排出されるように構成する。【選択図】図3
